论文摘要
研究了具有两种电流的固定跨通道系统中的输入和输出电流波动。在saryal {\ it等人} [phys。莱特牧师。 127，190603（2021）]，在线性响应制度中证明了输入和输出电流波动上的上限，并建议超出线性响应方案的有效性。我们检查了这些界限以外的线性响应制度，并发现这些边界在一般的非平衡固定条件下违反了。我们展示了两个例子来证明违规行为。通过这些示例，我们认为在线性响应方面不存在输入和输出电流波动的上限。
Input and output current fluctuations in stationary cross-transport systems with two kinds of currents are investigated. In Saryal {\it et al.} [Phys. Rev. Lett. 127, 190603 (2021)], upper bounds on input and output current fluctuations are proven in the linear response regime and suggested the validity beyond the linear response regime. We examine these bounds beyond the linear response regime and find that these bounds are violated in general nonequilibrium stationary conditions. We show two examples to demonstrate the violation. Through these examples, we argue that no upper bound on input and output current fluctuations exist beyond the linear response regime.
